In my eyes (Haikyuu Harem/ Mental Health)

The Story start off as a classic Harem FF, but as it progresses the underlining problems of (y/n) start to take influence on her thoughts and decisions more and more...

I myself struggle with mental health issues and decided to NOT put a trigger warning (no blood/no mention of selfharm/no suicidal thoughts etc.). If you also struggle with it I believe that you will find yourself in (y/n), if you don't have any experience with it, you maybe can learn about and see inside the mind of someone who does.
Disclaimer: I can NOT speak for everyone with mental health issues, so this is not universal
The way the other characters act and react to (y/n) is based on their personalities, as well as how I would imagine them to be.

You just moved to Japan late in the first semester of your secound High School year. You used to play vollyball, but since you injured your knee you stopped playing and startet to focus more on art. You've always been an exessive day dreamer and have a habit of processing your life through songs and humor inside your mind... no one else knows this of corse!!

How does it work? Everytime you hear a song in your head I will provide a link to the song on youtube, witch you then can listen to before you keep reading :D you don't have to, but it will supoort the story in some ways!!

I'm open for Critism ^^

*Haikyuu and it's characters don't belong to me, I'm only using them for my story*

Edit:
Like I already said, I also struggle with mental health, as well as the problems mentioned in the story as others. I did't want the story to be dark or heavy, because I feel like a fun story dealing with mental health is also interesting.
I kept (y/n) realistic, but I have to admit, that the other characters might be a little idealistic, but I mean it's a FanFic after all hahahaha
